单泛额外维模型中B-> K_{1} l ^{+}l ^{-}衰变的唯一性

Exclusive B-> K_{1}l ^{+}l ^{-} decay in model with single universal extra dimension

Ishtiaq Ahmed, M. Ali Paracha, M. Jamil Aslam

摘要:

在普适额外维(UED)模型下计算了B -> K_{1} l^{+} l ^{-}(K_{1}为轴矢量介子)的衰变率和前后不对称性.研究了这些物理量对UED模型中唯一未知参数紧化半径$R$的依赖性,指出了前后不对称性的零点对UED模型的敏感性,因此它们可以成为建立UED模型预言的新物理的有用工具.将此工作简单地推广到B -> K^{*}l^{+}l^{-}。

英文摘要:

Decay rate and forward-backward asymmetries in B -> K_{1} l^{+} l ^{-}, K_{1} is the axial vector meson, are calculated in the universal extra dimension (UED) model. The dependence of these physical quantities on the compactification radius $R$, the only unknown parameter in UED model, is studied and it is shown that zero of forward-backward asymmetry is sensitive to the UED model, therefore they can be very useful tool to establish new physics predicted by the UED model. This work is briefly extended to B -> K^{*}l^{+}l^{-}.
